SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No, 263,362, dated August 29, 1882.

Application Illed April 3, 1882.

To all whom it may concern:

Be it known that I, MA'rHnW A. Sra/rs, a citizen ot' the United States, residing atlVarrenton, in the county of Fauquier and State of Virginia, haveinvented anew and useful Spark ArresterandEXtinguisherandSmOke-I'uriiier, ot' which the following is a specification.

'The object of my invention is to arrest and extinguish the sparks and cinders and purity the smoke emitted from steam-engines, and at the same time increase the draft from the tirehoX to the point of discharge.

I am aware that it is not new to exhaust thc sparks and gases from the smoke-stack and to discharge them into water through the pumping-cylinder; but such soon gets out of' order and fails to operate, i'or the reason that the gases and sparks iirst pass into the air-pump before being discharged, and thereby cutting the cylinder or choking up the same to such an extent as to render it entirely useless. I

obviate this defect by first drawingthe sparksv and the heated gases through the water in the tank, and thereby cooling the gases that enter the cylinder,thus keeping the pumps cool and clean, and thereby in good condition at all times. I accomplish this object by means of devices which consist ot a combina-tion of pipes and tank, all arranged as shown and hereinafter described.

The accompanying drawings illustrate the principle, and show one method of attaching said machine to that class ot' engines called railroad-locomotives.77

Figure I represents a side View of a portion of a railroad-locomotive with the machine attached thereto. Fig. II represents an enlarged View ofthe tank and double-action pump and of the pipes connecting them.

Similar letters ret'er to similar parts throughout the several Views.

I attach to the smoke-stack X a short funnel, A, from which two pipes, B B, extend downwarchone on each sideof the boiler. Each pipe enters water C, contained ina tank, D, located between thc smokestack and the airpumps, near the cylinder and steam-chest. In the bottom of the tank is a discharge cock or door, E, connected by a rod with the en'- gineers room. Said tank is also connected (No model.)

by a pipe, F, with a double-action pump, G, and by a supplypipe, H, with the Water-tank in the tender. Connected with the doubleaction pump is the discharge-pipe I. The douhle-actien pump is worked by a pistonrod, K, attached to the cross-head of the enT gine. A pump, L, is also attached to the engine to supply the tank with water, and is operated by the cross-head or other moving part of the engine by which the desired stroke can be produced. ln many engines the water-supply may be regulated by a simple stop-cock.

N N N N represent the valves in thedoubleaction pump.

A door, O, in the top of the smoke-stack (or in the funnel) is connected by a rod with theV engineers room. The funnel in the drawings is att-ached to the top of the smoke-stack. It may he inserted in the side of the smoke-stack at any desired point, with a cut-oit' door or damper in the smoke-stack above it. The power may be applied to the piston of the double-action pump directly from the piston of the engine, or, where more convenient, as in many stationary engines, from the drivingwheel, axle, orshaftine.

The discharge-pipe I may be carried back into the furnace where the gases are consumed.

rIhe size of the pipes, tank, and double-action pump and their location will be determined by the character and size of the engine and the'drai't required.

Operation: When the engine is not in motion the cinders and smoke are discharged through the door in the smoke-stack, which is opened by the engineer for that purpose. When the engine is put in motion the door or damper in the smoke-stack is closed, and the doubleaction air-pumps, worked by the cross-head or otherwise, produce a continuous draft(increas ing with the speed ot' the engine) from the re-box through the lues, smoke-stack, pipes, and water inthe tank into the cylinder of the double action air -pump and out at the discharge pipe attached thereto. sparks, and impurities in the smoke are arrested in the water, and may be discharged at pleasure through the stop-cock or door in the bottom of the tank. The purified smoke or gases pass out through the discharge-pipe atrIhe einders,

2. A smoke and spark arrestingdevice consisting of the uptake, a reservoir having au inclined or conical bottom, an exhaustingpump, and an auxiliary watersupply pump, being connected to each otherand to the common cross-head or other moving part ot' the engine, all being arranged and combined in the manner set forth and described.
